摘要:Alcohol may be synthesized by treating olefinic hydrocarbons with carbon monoxide and hydrogen in a hydroformylation zone utilizing a rhodium complex catalyst to effect the reaction. Following formation of the alcohol, the catalyst may be extracted from the alcohol by treatment with an aqueous ammonium hydroxide solution. Thereafter the aqueous ammonium hydroxide solution containing the catalyst is then stripped of ammonia by treatment with carbon monoxide or carbon monoxide containing gas. The aqueous ammonium hydroxide solution containing the rhodium complex catalyst is then stripped of a portion of water and the remaining solution is thereafter recycled to the hydroformylation zone.

标 题 :Synthesis of alcohols by hydroformylation with nitrile promoter
发明人：IMAI TAMOTSU
权利人:UOP INC
摘要:Alcohols may be synthesized by reacting an olefinic compound, carbon monoxide and hydrogen in the presence of a Group VIII organometallic complex catalyst at reaction conditions which include a temperature in the range of from about 50° to about 250° C. and a pressure in the range of from about 10 to about 300 atmospheres. In addition, the reaction is also effected in the presence of a promoter compound comprising a nitrile.

摘要:A 1,1,1-trihalogeno-4-methyl-3-penten-2-ol is prepared by thermally isomerizing 1,1,1-trihalogeno-4-methyl-4-penten-2-ol. The isomerization reaction may be catalyzed by an acid or a transition metal of Group 6B, 7B or 8 of the Periodic Table of Elements, or a compound thereof. The 1,1,1-trihalogeno-4-methyl-3-penten-2-ol thus prepared is useful as a synergist for herbicides or a physiologically active compound, and, additionally, is useful as a starting material for the synthesis of 2,2-dimethyl-3-(2',2'-dihalogenovinyl)-cyclopropane carboxylic esters which are active ingredients of insecticides.
